Claims (4)

1. Hochspannungsschalter mit Lichtbogenbeblasung vom Typ des Druckgasschalters, der ein erstes Volumen (27) aufweist, in welchem der Druck durch die Heizwirkung des Ausschaltlichtbogens erhöht wird und das Gas sich zwecks Ausblasens des Lichtbogens im Augenblick des Nulldurchgangs des Stroms entspannt, und der ein zweites Volumen (37) aufweist, in welchem das Gas durch einen Kolben (39) am Anfang der Öffnungsphase des Schalters komprimiert und in den Folgephasen gegen den Lichtbogen gerichtet wird, wobei der Schalter feststehende Hauptkontakte (21), feststehende Funkenschutzkontakte (24), bewegliche Hauptkontakte und bewegliche Funkenschutzkontakte besitzt und der Lichtbogen sich in der Öffnungsphase des Schalters zwischen den Funkenschutzkontakten erstreckt, und wobei das erste Volumen (27) und das zweite Volumen (37) sich zu Seiten der Lichtbogenzone befinden, dadurch gekennzeichnet, daß die beiden Volumen ringförmig ausgebildet sind und in Düsen (26, 42) enden, welche getrennte Blasstrahlen jeweils auf jede der Lichtbogenwurzeln richten, wobei das erste Volumen (27) durch ein zu den feststehenden Funkenschutzkontakten koaxial liegendes Rohr (22A) und eine isolierende Düse (26) abgegrenzt ist, und das zweite Volumen durch ein erstes, den beweglichen Hauptkontakt bildendes Rohr (36), sowie ein zweites, koaxial zu diesem liegendes Rohr (35) begrenzt ist, und ein feststehender Kolben (39) das Volumen an einem Ende abschliegt.
2. Schalter nach Anspruch 1, dadurch gekennzeichnet, daß ein drittes, koaxial zum ersten und zweiten Rohr (36, 35) angeordnetes und den beweglichen Funkenschutzkontakt bildendes Rohr (34) zusammen mit dem zweiten Rohr (35) einen Ringraum (38) umgrenzt, in welchem sich ein viertes Rohr (41), das mit einer zweiten isolierenden Düse endigt, unter der Einwirkung eines Kolbens (43) verstellen kann der von einer Feder (44) bewegt wird, deren anderes Ende auf einem mit den beweglichen Kontakten fest verbundenen Anschlag (45) anliegt, wobei das dritte und vierte Rohr einen Durchtritt für das Gas des zweiten Volumens definieren, welches durch die Öffnungen (40,46) des ersten und zweiten Rohres tritt.
3. Schalter nach Anspruch 2, dadurch gekennzeichnet, daß die Ablösung der beiden isolierenden Düsen (26, 42) nach einer gewissen Verschiebung des Kontaktrohres (34) stattfindet, die nötig ist, um das thermische Volumen (27) auf Druck zu bringen.
4. Schalter nach den Ansprüchen 2 und 3, dadurch gekennzeichnet, daß die Öffnung (60) des thermischen Volumens senkrecht zur Achse des Schalter und zur Öffnung (50) des Kompressionsvolumens (37) steht.
